A36 Ss400 Iron Coil Cold/Hot Rolled Carbon Steel Coil
Cold-rolled steel coils have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling. High flatness, high surface finish, clean and bright surface of cold-rolled sheet. It is easy to be coated and processed and has the characteristics of high stamping performance and low yield point, so cold-rolled steel coil has a wide range of uses, mainly used in automobiles and building materials. At the same time, it is also the substrate for the production of galvanized steel sheets in coil and galvalume steel coil.
Carbon Steel Details:
Common carbon steel grades: Q195, Q215, Q235, Q255, Q275, etc.
Carbon alloy steel: 1008(08F), 1010(10#), 1015(15#), 1020(20#), 1025(25#), 1040(40#), 1045(45#), 1050(50#), 15Mn, 20Mn, 30Mn, 40Mn, 45Mn, 50Mn, etc.
Carbon tool steel: T7, T8, T8Mn, T10, T11, T12, etc
Each Carbon Steel Coil is being produced with care to quality by decreasing carbon contend and giving appropriate heat treatment.
Even distribution of steel coil various grades of carbon steel coil in accordance with ASTM JIS DINEN etc.
There is large amount of spot inventory and each carbon steel coil is subjected to modern physical and chemical testing.
Our Hot- and Cold-Rolled Stainless Coils are available up to 2 meters wide and in a number of grades: austenitics (S300), austenitics containing manganese (S200), duplex, KARA ferritics (S400) and martensitics.In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo annealing, solution treatment, aging treatment and other heat treatments before delivery. The corrosion resistance of stainless steel coils mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of the stainless steel coils. The main role is chromium. Chromium has high chemical stability and can form a passivation film on the surface of steel to isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases.

The application fields of cold-rolled coils are very wide, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc.
The product size of cold-rolled coils is accurate, the
thickness is uniform, and the thickness difference of the
coils generally does not exceed 0.01-0.03mm or less,
which can fully meet the requirements of high-precision
tolerances.
- vailable to extremely thin strips that cannot be produced by hot rolling (the thinnest can reach 0.001mm or less).
The surface quality of cold-rolled products is superior,
and there are no defects such as pits and pressed iron
oxide scales that often occur in hot-rolled coils. And
according to the requirements of users, it can produce
coils with different surface roughness (glossy surface or
hemp rough surface, etc.) to facilitate the processing of
the next process.
The mechanical properties and technological
properties of cold-rolled steel coils are very good (such
as higher strength, lower yield limit, good weight deep
drawing performance, etc.).
High-speed rolling and full continuous rolling can be
realized, with high productivity.
1. Appearance and surface quality: Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate. The hot plate is divided into the pickling plate and the unpickling plate. The surface of the pickling plate becomes the normal metal color because of pickling, but the surface of the unsold-rolled plate is not as high as that of the cold-rolled plate, or the existence of ferrosoferric oxide layer, colloquially it is fire-roasted, and if the storage environment is not good, usually with a little embroidery.
2. Properties: In general, the Mechanical Properties of hot and cold-rolled steel coil are considered to be the same in engineering, although there is a certain amount of work hardening during cold rolling, (but not rule out the case of strict mechanical performance requirements, it needs to be treated differently), cold-rolled steel coil usually than hot plate yield strength slightly higher, surface hardness is also higher, how specific need to see cold plate annealing degree. However, the strength of the annealed plate is higher than that of the hot plate.
3. Forming performance: Because the performance of cold and hot-rolled steel coil is basically not too much, so the forming performance of the influence factor depends on the difference of its surface quality, because the surface quality is the cold-rolled steel coil to be better, so generally speaking the same material steel plate, the appearance of cold plate is better than that of the hot plate.
